Batteries are patronized by those people who uses small devices such as when installing outdoor solar lights. Cells are also suitable for daily use to those who wants to maintain stunning solar lights in a very cost-efficient and Eco-friendly way.

How Does It Work

Solar batteries are essential parts of solar lights. Its main role is to convert and store the solar energy into electrical current.

A cell is the center power unit of a battery. It is compose of two electrodes and an electrolyte. Negatively charged electrons (anode) as well as the positively charged spaces (cathode) is being formed through the help of a crystalline silicone and chemicals.

Once the solar panel absorb sunlight and store it to a cell, the negatively charged electrons started to move until they reach the positively charged spaces. These chemical reactions allow formation of electrons along the negatively charged electrons.

Then the electricity produced is stored in a battery after positively charged spaces transmit electron by the wires. As the darkness arrives, the battery provides electricity to the solar lights to make them perform well.

Likewise, once the battery is connected to solar lights chemical reactions occur. As a result, all electrons and ions start to flow smoothly. Usually, electrons travel faster towards the positive electrode by the outer circuit.

The charging and storing process of a battery repeats as a daily cycle as long as the solar panel is exposed into abundant sunlight. The charging capacity of a cell may also be influenced by the location where it is placed.

What Are The Different Types Of Solar Light Batteries


There are different types of batteries that work best for solar lights. It is important to determine what kind of cell is being used in solar lights to determine which one is more compatible and let your solar lights produce maximum performance. Batteries vary from the chemical compositions that they are made of. Below is some of the cells ideal as a perfect match to a solar light.

  1. Nickel Cadmium (NiCd) Battery – This is a type of rechargeable cell that is often used for small and portable devices such as of computers, toys, cameras and solar lights. It stores energy through the help of electrodes. Said electrodes are made-up of metallic cadmium, an alkaline electrolyte of potassium hydroxide and nickel oxide hydroxide.

What unique about NiCad batteries is that it remains at a voltage of 1.2v until it run out of power. Hence, it is more effective to supply full power. A NiCad battery can work for up to 1,000 cycles before it totally dies.

  1. Nickel-Metal (NiMH) Hydrate Battery – Solar lights and other cordless device usually use NiMH batteries. It is believed to be safer to use than the NiCd batteries because the latter can be hazardous to environment without proper disposal. A NiMH cell can charge for up to 500 to 1000 times or equivalent to 2 or 3 years if used in proper way. The trick is it works longer when frequently use.
  2. Lithium ion (Li-ion) Batteries – Another type of rechargeable battery is the Li-ion. It started to flourish in early 1990s. Compare to Nickel Cadmium, it has a double energy density. It can also be noticed that Li-ion batteries weigh light and looks thin.

The advantages of Li-ion among the other batteries are that it has higher energy density, long lasting to use, and low self-discharge and low maintenance. Expect these cells to be more expensive too.

Advantages And Disadvantages Of Solar Light Batteries

The following downsides do not apply to all batteries, but they are the general take on these batteries. Keep reading for better information about them.

  1. Expensive– The solar energy stored in batteries are free except when long darkness or cloudy days come. During the times when sunlight is poor, users are buying ready to use power cell from nearby stores to light up their solar lights or other gadgets. And some batteries cost very expensive depend on the size and frequency.
  2. Replacement – While batteries are rechargeable for the longest time, it is also a well-known fact that cells are replaceable for at least every year. Aside from it adds to cost or budget of users, it is also hassle to do the battery replacement on a regular basis.
  3. Improper Disposal Cause Treat to Earth – It’s a well-known fact that batteries are made of chemicals such as lead, lithium, cadmium and mercury. These elements can cause pollution to the soil and water if batteries are not recycled or disposed properly.
  4. Safety issues – Batteries may explode when not properly used. Cells hate being overheat or overcharged as they have the tendency to malfunction and burst impact.

How We Picked And Tested


Every couple of months, we clean up our homes to get everything ready for the upcoming season. We also check on our lights to make sure that everything is working.

If your solar lights do not work the same way as it used to, or if it stopped working entirely, then it is time to get a new rechargeable battery.

Before you open your solar lights to clean it up, you need to check all of the solar light’s components.

The panel on each solar light needs to be cleaned because dirt can accumulate, and it can stop solar energy from getting through; thus, your lights may not charge properly.

After thoroughly cleaning your solar lights, make sure that it is faced directly towards the sun, or it should be placed in an open area where it can get direct sunlight.

Another component of your solar lights that you need to check is the battery. You can open the battery compartment and look for water damage, broken wires, or if there is rust that is building up.

Make sure that the batteries of your solar lights are connected firmly, and there should be no corrosion.

Solar lights have charge controllers or circuit boards that are responsible for the automatic on and off feature.

Once sunlight touches the solar panel, the board automatically sends the charge to the battery.

When nighttime comes, the sensor or circuit board knows that there is no solar energy anymore, and it stops charging the light’s battery. It then sends power from the light’s battery to the LED light.

If your solar lights do not work as well as it used to, sometimes all you need to do is to clean everything properly, and it will start working again.

If it still does not work, you need to check on the LED light. Try taking the battery off and put it back on again. You can also place the light in a dark room and see if it will light up.

If it still doesn’t work, then you need to get a new light and replace the battery.

Worn out batteries is one of the reasons why solar lights will suddenly stop working.

You need to replace the batteries so that the solar panel can continue to use solar power to charge your light batteries.

Not everyone is aware that you can replace the rechargeable batteries in your solar lights.

To make sure that your solar lights will not fail when you need them the most is to replace the rechargeable batteries regularly.

Do not wait for it to be completely worn out before getting a new one. It is advised to replace your batteries at least every two years.

Almost all kinds of solar lights use the same low capacity batteries. You can talk to an expert regarding the different capabilities and sizes of rechargeable batteries, and what brand of solar lights are compatible with them.

The most common battery is AA, but some lights require AAA. Depending on the brand of solar lights that you have, there are those that need rechargeable batteries that are difficult to find, like 2/3AA or 2/3AAA.

If you are going to replace the rechargeable batteries of your solar lights, remember to use the same capacity and the same voltage for it to work properly.

You can check the mAh rating of the rechargeable battery that you have so you will know the type of battery with which you need to replace it.

Using batteries that do not have the same voltage and capacity as what is recommended may result in a fried circuit board, and it can break your solar lights.

If you can’t find a rechargeable battery with the same voltage and capacity as the original, you may use a battery with mAh capacity that is a bit different than the original. Just make sure that it has the same voltage.

Choose a battery that has the nearest mAh rating as the original battery. You can check on the solar light’s manual or online for a guide on rechargeable battery capacity and rating.

Once you’ve bought a new rechargeable battery for your solar lights, you can install them right away, but it can take a couple of days before your lights will work again.

If they still won’t work after a couple of days and after checking the components, then it is time to replace your lights.

We are told to believe that the higher the capacity of the battery, the better it is for the lights, but that is not always the case.

Rechargeable batteries that have high capacities need higher current to get them to charge properly. Solar energy produces low current, so it is best to use batteries that have low capacity.

Also, do not use a non-rechargeable battery in solar lights that are rechargeable, because it will not work, and it may damage the circuit board.

Frequently Asked Questions


Are all batteries compatible with solar lights?
